3 Overview

3.1 Purpose Reverse torsion measuring mechanical properties of materials and finished products is mainly used, it can also be used for materials and finished products Reverse destruction performance tests. 3.2 Principle structure Twisting machine according to torque (even) the principle of balance work, can have a variety of structural forms, but shall have torque measurement Institutions, and the holding torque is applied to the system by means twisting the specimen. Need to give a sample torsion angle twisting machines should be equipped with clip Head angle measuring device or reverse the count.

4 legal management requirements

4.1 units of measurement Reversing the machine should be legal units of measurement. Bovine torque units [Dayton] meters (symbol. Nm) and its multiples or fractions of units. Corner (or torsion angle) units in degrees (symbol. °) and its multiples or fractions of units. Speed unit using rpm (symbol. r/min) and its multiples or fractions of units.
